Su Yu's words sent a sudden jolt through Kakashi's heart.
That was indeed something he couldn't explain.
Back then, when Rin had died by his hand in an accident, he had felt a burning sensation in his left eye. Afterward, he discovered that the eye Obito had given him had awakened the Mangekyō Sharingan.

Normally, Kakashi was merely a slacker, but now he looked
